UK air traffic control chief summoned by transport secretary as flight chaos spreads

Martin Rolfe, chief of air traffic control provider Nats, has been summoned to meet UK Transport Secretary Heidi Alexander as flight cancellations reached 1,300 on Wednesday, the second consecutive day of major disruptions affecting hundreds of thousands of passengers.

Rolfe is facing increasing pressure to step down following what officials describe as the third major air traffic stoppage in just over three years. He is scheduled to brief Alexander on the ongoing crisis.
